As part of a continued research project for the Utah Water Research Laboratory and the State of Utah, a study of flow measurement devices is being conducted throughout the state. Initially the project included only measurement devices associated with high-risk dams, but has since been broadened to any measurement structure of interest for water users in the state. The physical dimensions, relative elevations, and flow accuracy were documented for each included device.
After visiting sixteen sites, it was found that fourteen of the measuring devices had incorrect geometries. Of these fourteen, thirteen of them were originally Parshall flumes. A large …

The Utah Water Research Laboratory, in conjunction with the State of Utah, initiated a study to determine the accuracy of a wide variety of flow measurement devices in Utah. The project selected 70 sites with flow measurement devices throughout the state. During the assessment each device had its physical condition and flow measurement accuracy documented.
Although a wide variety of flow measurement devices were tested, the majority were Parshall flumes. Many of the assessed Parshall flumes were not measuring flow to the specified ±5 percent design accuracy. Problems in flow measurement were due to issues with the staff gauge location …
